Title: Improvements in or relating to aircraft
Inventor: KENMIR CHARLES VIVIAN
IPC: B64C29/00
Filed: 1958-03-11
Abstract: 869,632. Direct lift aircraft. BOULTON PAUL AIRCRAFT Ltd. June 9, 1959 [March 11, 1958], No. 7881/58. Class 4. In an aircraft, in which direct lift is provided by a fan system driven by the efflux from one or more jet engines and means, such as louvres at the fan duct outlet, are provided for deflecting the fan discharge forwardly or rearwardly to provide a horizontal thrust component, the effective cross-sectional area of the fan duct increases progressively between the fan and the outlet to avoid loss of thrust during deflection. The lower part of the fan hub is tapered as shown to provide a crosssectional area at the outlet plane of the louvres (which for vertical lift are coned inwardly as shown). which is substantially the same as the cross-sectional area of the duct at the fan. The movement of the louvres simultaneously in the same direction to deflect the airflow, Fig. 3 (not shown), will produce substantially an equivalent cross-sectional area at the louvre outlet. In an alternative embodiment the hub is cylindrical and the outer wall of the duct between the fan and the louvres is flared outwardly or both hub and outer wall may be flared.

Title: Improvements relating to the control of electric motors for traction purposes
IPC: B60L7/12
Filed: 1922-03-18
Abstract: 198,127. Ferguson, T., and Metropolitan-Vickers Electrical Co., Ltd. March 18, 1922. Regenerative systems.-In systems for regenerative braking of one or more traction motors wherein the field windings 2 of the motors 1 are excited by a separate generator 8, the field winding 10 of the exciter generator 8 is supplied from an auxiliary exciter 20 having its field 12 automatically regulated in accordance with the speed of the driven vehicle. This may be effected, as shown, by centrifugal action of an axle upon a rheostat 15, the resistance decreasing as the speed increases in order to increase the braking efiect. The rheostat is preferably of the type described in Specification 26646/13, [Class 38 (v), Electric switches &c.], in which a rotating contact disc engages with a movable brush. The braking effect may be independently varied at will by resistances 13 controlled by contactors 14. For trains with several motor vehicles, the regenerative effects are equalized by arranging the circuits so as to regulate the excitation equally and simultaneously on all the vehicles. Extra resistances may be cut-in and cut-out to compensate for the difference between series and parallel working of the main motors.

Filed: 1925-03-30
Abstract: 253,642. Bramson, M. L. March 30, 1925. Balancing. - A device for warning the pilot of an aeroplane through the sense of touch when the angle of incidence reaches a value at which stalling may occur, comprises means for suddenly applying a force to the control lever in a direction to cause a reduction of the angle of incidence, this force being sufficient to actuate the controls but weak enough to be resisted by the pilot if he so desires. The means for appiying the force comprises a rod universally jointed to the control lever and connected to a piston 3 working in a cylinder 4 which is universally pivoted to a bracket 9 on the machine framework. One side of the piston is permanently open to the atmosphere through holes 5 but the other communicates with a relay valve chamber having a double valve controlled by a diaphragm 14. Compressed air from a conduit 17 normally leaks through a by-pass 18 and adjustable port 19 to a chamber 13 and the valve opens the cylinder to atmosphere through holes 16. When however. the chamber is vented through the conduit 20 the valve moves to close the cylinder and admit compressed air. The conduit 20 is connected by flexible tubing to a hollow member 24, Fig. 5, adjustably mounted on a bracket 26 attached to a wing strut. A vane 21 is carried by a member 22 pivoted to the member 24 at 23, a screw stop 29 providing a fine. adjustment. The vane 21 extends upwind so that when a predetermined angle of incidence is reached the arm 22 moves upwards and opens a valve 31 in the member 24 thereby venting the chamber 13, Fig. 3. The arm 22 will remain in its upper position until the angle of incidence of the machine is diminished by an amount equal to the angular movement of the arm between its stops. The device may be put out of action by a valve in the connection between the conduit 20 and the member 24.

Title: Improvements in or relating to the separation of straight chain hydrocarbons from hydrocarbon mixtures
IPC: C10G25/03
Filed: 1960-03-11
Abstract: In the employment of 5 Angstrom molecular sieves to separate straight chain from branched chain and/or cyclic hydrocarbons, the hydrocarbon feedstock mixture in the vapour phase is passed over the sieve together with a purge material and the feedstock flow is halted, preferably at breakthrough, whilst the purge stream is continued, the total purge volume being from 0,25 to 3 times the volume of feedstock.  Conventional desorption is effected in a third stage. The preferred feedstocks are petroleum distillate fractions boiling above 200  DEG C., especially gas oil fractions boiling at 200-350 DEG C.; pretreatment to reduce the sulphur content to 0,1% or below is desirable.  The purge material, which has a boiling range different from that of the feedstock, may be polar or non-polar and its molecules preferably have critical diameters greater than 5 . Examples are benzene, toluene, iso- and cycloparaffins, and methyl isobutyl ketone. C1-C5 paraffins such as n-butane or n-pentane or inert gases such as nitrogen may also form the purge.  The adsorption purge step may be carried out in fixed or moving beds and desorption may be effected with normal paraffins.  Pressures for the absorption-purge may be 100-300 p.s.i.g. and 0-250 p.s.i.g. for desorption.  An example refers to gas oil containing 24% n-paraffins contacted at 400  DEG C. and 150 p.s.i.g. with the 5  sieve in admixture with benzene.  Benzene flow was continued after the feedstock flow was halted until the total volume of benzene fed was 2 1/2 times the volume gas oil fed.  Nitrogen was then fed at atmospheric pressure and 400  DEG C. to recover benzene from the sieve surface and adsorbed n-paraffins were finally desorbed with n-heptane at 400  DEG C. at atmospheric pressure. Specification 898,059 is referred to.
